Sketch the following to help answer the question. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals

Troyanec [42]

Answer:

B. 8m

Step-by-step explanation:

Given:

The figure is a kite having points QRST.

It has short diagonal QS.

Long diagonal RT

Diagonal Intersect at point P.

side QR = 10m

Diagonal QS = 12m

We need to find the length of segment RP.

According Diagonal Property of kite.

It states that Diagonals of Kite perpendicularly bisects each other.

QP = PS

RP = PT

But QS = QP + PS

QS = QP + QP

QS = 2 QP

QP = $\frac{1}{2}$ QS = $\frac{1}{2}\times 12 = 6 m$

Now In Δ QPR

m∠ P = 90° (Diagonals of a kite is perpendicular to each other)

Now by Pythagoras theorem;

$QR^2 = QP^2+RP^2\\RP^2 = QR^2 - QP^2\\RP^2 = (10)^2- (6)^2\\RP^2 = 100 -36\\RP^2=64\\RP = \sqrt{64} =8\ m$

Hence the Length of segment RP is 8m.

SHOW YOUR WORK 9 ÷ 4.5 = ?

Dahasolnce [82]

Answer: 2

Step-by-step explanation:

Change the divisor 4.5 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

90 ÷ 45 = 2

and therefore:

9 ÷ 4.5 = 2

The table of values shown below represents a linear function. Which of these points could also be an ordered pair in the table,

maks197457 [2]

Answer:

(18,27) , because the rate of change of the function is $\frac{4}{3}$

Step-by-step explanation:

step 1

Find the slope of the linear equation

Looking at the table

we have the points (0,3) and (3,7)

The slope is equal to

$m=(7-3)/(3-0)=\frac{4}{3}$

step 2

Find the equation of the line in slope intercept form

$y=mx+b$

where

m is the slope

b is the y-intercept

we have

$m=\frac{4}{3}$

$b=3$ -----> point (0,3) is the y-intercept

substitute

$y=\frac{4}{3}x+3$

The rate of change of the linear equation is equal to $\frac{4}{3}$

Remember that

If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation

Verify

1) point (18,27)

substitute the value of x and the value of y in the linear equation

$27=\frac{4}{3}(18)+3$

$27=24+3$

$27=27$ -----> is true

The ordered pair is a solution of the linear equation

therefore

The point (18,27) could also be an ordered pair in the table

2) point (27,18)

substitute the value of x and the value of y in the linear equation

$18=\frac{4}{3}(27)+3$

$18=36+3$

$18 \neq 39$ -----> is not true

The ordered pair is not a solution of the linear equation

therefore

The point (27,18) could not be an ordered pair in the table
